HEADER Foe STEAM-BOILERS;

SPEGIFIGATION forming part of Letters Patent No.738,563, dated September 8, 1903.

Application filed October 25, 1902.

To a whom itmayconcern; l u

. Be it known that I, EDWARD J MOORE, a citizen of the United States, residing in the city and county of Philadelphia,State of Pennsylvania, have invented a new and useful Improvement in Headers for Steam-Boilers, of

which the following is a specification.

My invention consists in improvements in i various particulars in headers for water-tube boilers whereby the capacity and efficiency of the boiler are increased and the cost of manufacture lessened; I also make provision for assembling the various parts in a more com- ,pact and economical manner, whereby the headers are strengthened, a maximum area of heating-surface attained, and means are provided for enabling the cleaning of the tubes to'be readily accomplished, all as will be hereinafter set forth.

My inventionfurther consists of novel features of construction, all as will be hereinafter set forth.

Figure 1 represents a vertical sectional vie of a header embodying my invention. Fig.2 represents a front elevation of Fig. 1. Fig. 3

represents a section on line a: m, Fig. 1. Fig.4

represents a rear elevation of Fig. 1. Fig. 5 represents a sectional view of a pair of headers in assembled position. Fig. 6 represents a vertical sectional View of a vertical or upright header having a stepped rear portion. Fig. 7 represents a sectional view of an inclined header having an upper row of tubes extending in'a horizontal direction and a,

lower row of tubes extending inaninclined direction. Figs. 8 and 9 represent, on an enlarged scale, front elevations of headers,

showing the closures therefor. Figs. 10 and 11 represent sectionalviews of headers, showing holes through the webs thereof for the insertion of a cleaning-pipe. Fig. 12 represents a plan view of Fig. 10. Fig. 13 represents'a section on line y y, Fig. 11. Figs. 14

the rear wall 3 and the sinuous side walls 4,

the relative position of the headers when assembled being understood from Figs. 2, 3, and 4, it being understood that by shaping said side walls in sinuous lines I am enabled to lay them up side by side and by their curves to give them strength to carry a high pressure of steam. It will beseenfrornFigs. 2 to 4 that each header has alternate wide and narrow portions in which I place, respectively, two holes 5 and one hole 6, whereby I am enabled to construct a continuous staggered header with more than one row of holes in its back wall 3 in order to increase the capacity andstrength of the header. This arrangement allows the making of. the walls of the header thicker and gives it strength to resist internal pressure. In order to obtain a large amount of effectual heating-surface, I taper the side walls 3 of the header from front to rear, as indicatedin Fig. 5, so that the hot gases have every opportunity to impinge upon a maximum heating-surface of the headers, thereby. increasing the horse-power of the boiler to a large extent, the extent of this taper being understood from Fig. 5 and thedotted lines seen in Fig. 2.

7 designates oblong plates having rounded ends and provided with flanges 3 around them, adapted to hold any suitable material to make a steam-tight joint on the inside of the headers. When the joints are made on the outside, there is endless grinding of the seats to be done to keep them tight; but with my arrangement when the joints are once made up the pressure tends to keep them tight indefinitely.

9. designates bosses or ribs constructed around the out-side margin of the oblong hole on the front of the header, similar bosses being shown on various parts of the headers,

loo

forcing the holes in said headers, as will be apparent. 7

1O designates webs of iron located between the alternating holes 5 and 6, which, as I have already explained, I arrange in staggered order, two and one in cross and vertical lines, said webs having the openings 11 therethrough to allow the passage of water and steam and to protect the headers from rupture or destruction from overpressure, as it is necessary to provideagainst accident on account of the general demand for high steam-pressure, which is the tendency of the present time. Each of the apertures 11 in the webs 10 is provided with the print-openings 12 to allow a passage for the stopper 7 to pass through from the inside of its oblong hole to its place to secure the joints of the single hole in the header.

13 designates a series of holes extending through the webs and passing through the front and'rear wall of the header and the interior space 'thereof, said hole being large enough to pass a pipe through to sweep off the dust from the exterior of the tubes. When this is a part of the web, it does not add to the weight of the header, but tends to give strength to the structure, and by this arrangement of making provision for cleaning the tubes from the front and rear of the boiler less'room is required in the vessel or on land service. In the header seen in Fig. 1 I have shown the top portion 14 as constructed on a level line or boss, so that a tube can be inserted or coupled thereto at any angle, so that if the header is raked to any degree the circulating-tubes will be in a vertical position. This construction renders the sediment from the water not so likely to ad here to the vertical circulating-tube, makes the boiler more efficient, and tends to increase the life of the tubes.

In Fig. 7 I have shown the header 15 as adaptedto be used for a cross-drum type of water-tube boiler, in which case the header is placed in an inclined position from the ver-' tical, and at the same time the upper row of tubes 16 must extend in a horizontal line, while the tubes 17 below them are in an inclined position. The upper tube or tubes 16 are secured in the boss or bevel portion 18, whereby the structure is not weakened; but

- the strength of the headers is increased and bending of the tubes at this point is prevented. It will be apparent that the construction just described makes it just as easy to clean or insert a tube in this upper row as any others coupled to the headers.

In Fig. 6 I have shown a preferred form of construction of my novel continuous staggered headers wherein the header 18 stands in an upright position, so that the tubes 19 may be horizontally inclined. For this purpose I step the rear wall 20, that the tubes 19 are coupled to,and also the front portion of the wallof the header, as well as the perforated Web 21 on the interior. This construction makes the header fully as strong as if it was raked in the usual way, with the further advantage that it lessens the space occupied by the boiler as much as two feet in length, this being an important feature among those which constitute my improvements in headers for steam-boilers of the wator-tube type.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is j 1. As an improved article of manufacture, a continuous integral staggered double header having more than one row of tubeholes in its back wall and a series of perforated webs between the holes and openings extending through the webs at right angles to the perforations thereof.

2. As an improved article of manufacture, a continuous integral staggered double header having a series of perforated webs a continuous integral staggered header hWfi,

ing alternating holes in its vertical walls as two and one in combination with perforated webs between the holes, and said webs having openings at right angles to the perforations thereof, as and for the purpose specified.

4. In a continuous integral staggered header a'series of webs in the interior of the header said webs having perforations and openings at right angles to such perforations and for the purpose specified.

5. In a continuous staggered header a series of webs having perforations in said webs for the passage of water and'steam and one or more openings in said webs reaching from the front wall to the rear wall of theheader, as and for the purpose specified.

6. A continuous integral staggered header designed to be placed in an inclined position having front and rear walls and perforated webs stepped, and a boss or hub on the upper hole or holes, as and for the purpose specified.

7. As an improved article of manufacture, a continuous staggered header having webs provided with apertures and each aperture provided with print-openings, as and for the purpose specified.

8. As-an improved article of manufacture, a continuous staggered header having webs provided with apertures and each aperture provided with print-openings, and a stopper for cooperation with the said openings, as and for the purpose specified.

9. As an improved article of manufacture,
